Thanks Joern, this was very helpful and has resolved my crashing problem with PMH.
I hope someone from Sony is seeing this thread and can now recongnize that the application is flawed and that this was not a figment of our imagination.
I am not certain that I understand what you did with the files once you got PMH up and running again.
Please explain further what you meant when you moved the photos and aperture libraries in an own folder in the pcitures folder.
What do you mean by aperture librairies?
Thanks your persistence in resolving this problem...
